Subject: Re: Need help configuring my network
I also noticed the following error is reoccurring every few seconds when I run
dmesg:

ath0: no IPv6 routers present

I have googled around for this error and to may have something to do with
wpasupplicant. But I cannot seem to find a fix for it.

Any ideas?

Thanks!
